Fishing tool



' Patented y'July 14, 1942 UNITED STATES PATENT OFFICE FISHING TOOL'Hasca Dixon, Paintsville, Ky.

Application March-14, 1942, Serial No. 434,745 l 1 Claim.

This invention relates to fishing tools for removing lost objects, toolsand the like from wells which are under construction or being drilled'togreater depth sand more particularly to a shoe for' a tool of thecharacter specified and which may form a part of said tool or may beattachable thereto for the purpose of guiding into the tool -a lostdrill, a broken drill rod or any other L lost object in the well whichmay have assumed a position of leaning against a wall of the well Whileresting on the bottom of said well, so that time andy labor will lbereduced to a minimum in bringing the tool in gripping relation to thelost object.

With these and other'objects in view as will become more apparent as thevdescription proceeds the invention consists in certain novelfeatures ofconstruction, combination and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa side elevation partly in section illustrating a fishing tool equippedwith a shoe constructed in accordance with my invention and showing thetool within a well prior to bringing the tool into engagement with alost object.

Figure 2 is a view lsimilar to Figure 1 showing the vapplication of thepresent invention to another type of fishing tool from that shown inFigure l.

Figure 3 is a vertical sectional view illustrating one of the tines orguides of the shoe. Figure 4 is a sectional view taken on the line lf-lof Figure 1.

Referring in detail to the drawing, the numeral 5 indicates a well, G alost object in'said well and 1 a'iishing tool/oi thetype employingspring. influenced gripping jaws 8 arranged internally thereof. Thespring for influencing` the jaws I is indicated by the character 9 andmay have the tension thereof varied by a wedge I0.

A fishing tool of this character is extremely ineiilcient in that it ispractically 'impossible to bring a lost object into engagement with thegripping jaws when the tool is lowered and when said object is occupyingan upright tilted position. Much time and labor is lost in attempting toremove an object thuspositioned with'a tool of the kind described andshown. I n order that including a body I2 provided with V-shaped cutoutsforming substantially V-shaped tines or prongs I3, each arcuately curvedand provided with beveled faces I4 leading inwardly from the free edgesof said tines or prongs.

The tool equipped with a shoe II of the character described will readilyposition'the lost object 6 in an upright position as the tool is loweredinto engagement with saidobject, so that on further lowering of the tool1 the object 6 will be guided into engagement with the gripping jaws 8and become tightly gripped thereby s'o that on raising of the tool 1from the well the lost object 6 will be removed from the well alongwr'g'i the tool. i

By reference to Figure 1 it will be seen that the pointed ends of thetines I3 will occupy positions in closeproxix'nity to the walls of thewell vas the tool 1 is lowered so that said pointed ends may movebetween the lost object 5 and the wall of the well and bring aboutrighting of the lost object asv the tool is lowered and further guidethe object vinto engagement with the gripping jaws to be grippedthereby.`- l,

While the shoe has been shown and described in connection with Figure 1as forming an in.. tegral part of the'tool 1, the body II may beinternally screw threaded, as shown at Il, so that said body may bethreaded onto the lower end of the iishing tool as shown in Figure 2;This figure also shows another #type of fishing tool from that shown inFigure l and is indicated in entirety by the character I5.

The tool I5 is of the frictional gripping type and includes a taperedbore I6 opening outwardly through its lower screw threaded end I'I. Thescrew threaded end I'I of the tool I5 has the body Il of the shoethreaded thereon. The shoe thus applied to the tool I5 will efficientlybring a lost object from an inclined position into a perpendicularposition and guide the same into the bore I6 so that as the tool I5 islowered further with yrelation to the lost object, the latter becomesthe tool `may be made elcient, the present inl vention is formedintegrally with its lower end. The present invention isindicated inentirety by the character II and is in the form of a shoe tool thereto.

a wedge shaped pin I1 may beitted. By the use of the present inventionin the manner described, will obviate the necessity of the comm'anpractice of using a wall hook to straighten up the lost object .whenattempting to adapt the While I have shown and described -the preferredlembodiment oi' my invention, it will be understood that minorchanges inconstruction, combination and arrangement of parts may be made withoutdeparting from the spirit and scope of the invention as claimed.

Having thus described my invention; what I of different diameters andthe possibility of catching on objects when lowered in a well, said bodyhaving V -shaped cutouts providing substantially V shaped prongs eachbeing arcuately curved transversely thereof and provided with taperedfaces extending from the edges thereof inwardly of said prongs, saidprongs lying in the plane of the exterior walls of the tool and actingto guide into the body and through the latter into the fishing tool anobject occupying a tilted position within a well.
